The study evaluated the implant bone loss and stability of implant changes with diverse designs with early placement at eight weeks and eight months' time. The subjects for the current study had partial tooth loss in the posterior mandibular arch. A total of 30 samples were split into two groups of 15, one with a flared crest module and a buttress thread design, the other with a parallel crest module and a V-shaped thread design. Ostell assessed each subject's implant stability four times, at baseline, eight weeks, four months, and eight months. At intervals of eight weeks, four months, and eight months, intraoral periapical radiographs were examined using ImageJ software to measure crestal bone loss. When Group I and Group II's implant stability quotient (ISQ) values at baseline, eight weeks, four months, and eight months were compared; Group I's ISQ values at each of the four measured time periods were statistically significant. At eight weeks in Group I, the ISQ value was very considerable. At eight weeks, four months, and eight months, there was a statistically significant bone loss in Group II in comparison to Group I. At eight months, Group II's bone loss value was very considerable. In contrast to Group II implant designs, it was found that Group I implants demonstrated enhanced implant-less bone loss and stability.
该研究评估了在8周和8个月时早期植入的不同设计种植体的骨丢失和种植体稳定性变化。本研究的受试者在下颌后牙弓部分牙齿缺失。总共30个样本被分成两组，每组15个，一组采用扩口嵴模块和支撑螺纹设计，另一组采用平行嵴模块和V形螺纹设计。Ostell在基线、8周、4个月和8个月时对每位受试者的种植体稳定性进行了4次评估。在8周、4个月和8个月的间隔时间，使用ImageJ软件检查口腔内根尖片以测量嵴顶骨丢失。比较第一组和第二组在基线、8周、4个月和8个月时的种植体稳定性商（ISQ）值；第一组在四个测量时间段的ISQ值均具有统计学意义。在第一组8周时，ISQ值非常可观。在8周、4个月和8个月时，与第一组相比，第二组存在统计学意义上的骨丢失。在8个月时，第二组的骨丢失值非常可观。与第二组种植体设计相比，发现第一组种植体表现出更好的无种植体骨丢失和稳定性。
